When we hear about moving objects with electricity, most of us imagine a "pulling force." Positive and negative charges ...

This alternating electric field produces what are called dielectrophoretic forces, which are essentially a non-uniform electric field creating a traveling wave that pushes dust across the surface. By ...

A dead satellite can become a high-speed hazard in an orbit that is already packed with working spacecraft. That risk is why engineers at the University of Colorado Boulder are building what sounds ...

Researchers have discovered that ferroelectric fluids can harness an overlooked transverse electrostatic force (TEF) to rise over 80 mm, without magnets or high voltages. By exploiting the fluid's ...

Electrostatic Force Microscopy (EFM) and dielectric characterisation have emerged as pivotal techniques in the exploration of nanoscale phenomena, enabling researchers to probe the electrical ...
